A case of pulmonary tumoral thrombotic microangiopathy supported by VA-ECMO and a review of the literature.

We report a case of pulmonary tumoral thrombotic microangiopathy (PTTM) of pancreatobiliary origin who presented with fulminant right heart failure and was revived by extracorporeal membrane oxygenation-cardiopulmonary resuscitation (ECMO-CPR). Pathology of PTTM was illustrated. This case highlights the notorious difficulty of antemortem diagnosis of PTTM as well as the role of venoarterial-ECMO as a temporizing measure to diagnosis and treatment.
